Electrostatics, Part 4-3 - Footwear
This part of IEC 61340 describes a test method for determining the electrical resistance of footwear, with which the electrostatic potential on individuals is controlled. This standard is suitable for use by manufacturers of footwear as well as by end users.
Specifies the weight of a shoe in size 42 in grams (g).
